Answer» Two blocks of masses $5 kg$ and $2 kg$ are placed at rest on a frictionless surface and connected by a spring. An external hit gives a velocity of $21 m/s$ to the heavier block towards the lighter one. Velocities of both blocks (heavier and lighter one) in the centre of mass frame, just after the kick will be respectively: (Consider direction of motion of heavier block as $+ v e$ direction)
